Comparison of visual and molecular taxonomic methods to identify ichthyoplankton in the North Sea [PDF]

Limnology and Oceanography: Methods, 2020
AbstractThe North Sea is an important spawning and nursery ground for many demersal and pelagic fishes whose spawning areas are largely overlapping in time and space. This makes ichthyoplankton visual identification from the various species particularly challenging.

Extending GroupStruct2: a Bayesian and machine-learning framework for testing taxonomic hypotheses using morphometric data [PDF]

ZooKeys
Despite considerable advances in statistical methods, taxonomic delimitation using morphometric data (morphometric delimitation) has not significantly progressed beyond the use of simple summary statistics or univariate tests to quantify differences ...

Identification of pathogenic fungi causing ocular infections using full rRNA operon sequencing with Oxford Nanopore Technologies [PDF]

PeerJ
Although fungal eye infections are a major cause of visual impairment worldwide, standard clinical laboratory methods remain slow, insensitive, and limited in their taxonomic resolution.

Stable organization of the early lexical-semantic network in 18- and 24-month-old preterm and full-term infants: an eye-tracker study

Frontiers in Psychology, 2023
IntroductionAn organized mental lexicon determines new information acquisition by orienting attention during language processing. Adult-like lexical-semantic knowledge organization has already been demonstrated in 24-month-olds.
